Potholes

Potholes are more prevalent in the
spring when frost develops and snow is melting. Residents are warned to
be careful when going through puddles because they can hide potholes.
The Township does not repair potholes in driveways and private parking
lots.

The Formation of Potholes on hard surface roads

Water seeps into cracks in the pavement.

The water builds up and softens the ground under the road.

The water freezes and expands, which pushes the pavement up.

When the water under the pavement dries, a hole is left beneath the road.

The pavement is now weakened. As soon as a car drives over this area, the pavement collapses, leaving behind a pothole.

In the winter and spring when the
Township repairs the pothole, the material often does not adhere
sufficiently; therefore, the pothole may develop again quite quickly.
Once the weather permits, works staff will fill the pothole with more
permanent material.

Gravel Roads

Gravel roads are graded in the spring
as soon as the weather allows. Once dust suppressant is applied in June,
grading is avoided until September. Fall grading commences in
September, as needed, until freeze up.
